A 47-year-old man was killed by an out-of-control car after its driver lost consciousness leaving a car wash in Brooklyn, police said Friday.

The fatal incident unfolded just before 4:45 p.m. at Atlantic Avenue and Milford Street in Cypress Hills, where a car wash employee pulled the 2006 Liberty SUV off the lot, popped a U-turn and jumped the curb at the intersection, striking the man, according to cops.

Police believe the 63-year-old driver had a medical episode, causing him to lose control of the car. When cops arrived, the driver was unconscious, and he was transported to a nearby hospital for treatment.

The victim died at the scene, police said.
